To summarize, Labor Code § 3208.1 explains that the date of injury for cumulative traumas (CT), which determine when applicant’s statute of limitation is triggered and governed by Labor Code § 5412. That would be when the applicant has both disability PLUS knowledge that his or her disability is work related.

Labor Code § 5500.5 on the other hand explains what the CT date of injury would be with regard to determining carrier liability (either applicant’s “last injurious exposure” OR the date determined by Labor Code § 5412, whichever date arrives first).
